how to use switch to match datagroup

so if I use [string tolower [HTTP::uri]] many times,then,I need to use variable

 

but if I use [HTTP::uri] many times,then,I don't need to use variables,right?yes, that is what i understand.

 

 

If you were running an operation against a command multiple times you'd want to run it just once and then save the output to a variable.i understand operation means something such as string tolower ...

 

 

hope this helps.
